ABSTRACT:
The invention relates to the reproduction of high-fidelity multi-dimensional sound fields intended for human hearing. More particularly, the invention relates to the decoding of signals representing such sound fields delivered by one or more delivery channels, but played back over a number of presentation channels which may differ from the number of delivery channels. In a preferred embodiment, a decoder implemented by a discrete digital inverse transform incurs implementation costs roughly proportional to the number of presentation channels.
